| 摘 要： | 田螺山遗址是我国第一处实行原址保护和展示的南方古遗址,发掘后打破了遗址原来所处的稳定环境,导致遗址出现了一些病害。为了使得该遗址较好地保存下去,本文分析了该遗址土壤的理化性质,在此基础上,选用CB材料对该遗址土样进行了室内及现场加固试验。加固前后土样耐水性、PH值及强度等表征的对比表明,加固后的土样具有较好的耐水性,抗剪强度参数粘聚力有明显的增大,从而增加了土壤颗粒之间的粘聚力。现场小面积加固试验表明,保持了遗址原貌,渗透性好,未见表面开裂现象,同时强度也有很大的提高。

| Abstract: | The physical and chemical properties of the site soil were analyzed. The results indicated that soil granular structure was loose, suggesting that the soil aeration was very good, however, which could cause crack and collapse. The soil samples were reinforced by CB consolidating agent in the laboratory, a series of tests on the treated and untreated sample was carried out including water resistant, PH value and shearing strength, the results showed that the treated samples possessed excellent performance in... |
